Yinuo Han, Elias Mansell, Jeff Jennings +38
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) was recently completed to cover the lack of high-resolution observations of debris discs and to investigate the preva…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission
J. Milli, J. Olofsson, M. Bonduelle +33
Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) III: The vertical structure of debris disks
Brianna Zawadzki, Anna Fehr, A. Meredith Hughes +37
Debris disks -- collisionally sustained belts of dust and sometimes gas around main sequence stars -- are remnants of planet formation processes and are found in systems ${\gtrsim}…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): VI. Asymmetries and offsets
J. B. Lovell, A. S. Hales, G. M. Kennedy +33
Asymmetries in debris discs provide unique clues to understand the evolution and architecture of planetary systems.** The aim of the ALMA survey to Resolve exoKuiper belt Substruct…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) I: Motivation, sample, data reduction, and results overview
S. Marino, L. Matrà, A. M. Hughes +39
The outer regions of planetary systems host dusty debris discs analogous to the Kuiper belt (exoKuiper belts), which provide crucial constraints on planet formation and evolution p…
Chasing the storm: Investigating the application of high-contrast imaging techniques in producing precise exoplanet light curves
Ben J. Sutlieff, David S. Doelman, Jayne L. Birkby +10
Substellar companions such as exoplanets and brown dwarfs exhibit changes in brightness arising from top-of-atmosphere inhomogeneities, providing insights into their atmospheric st…
Hot exozodiacal dust around Fomalhaut: The MATISSE perspective
Kevin Ollmann, Florian Kirchschlager, Thomas A. Stuber +6
Excess over the stellar photospheric emission of main-sequence stars has been found in interferometric near-infrared observations, and is attributed to the presence of hot exozodia…
REsolved ALMA and SMA Observations of Nearby Stars (REASONS): A population of 74 resolved planetesimal belts at millimetre wavelengths
L. Matrà, S. Marino, D. J. Wilner +19
Planetesimal belts are ubiquitous around nearby stars, and their spatial properties hold crucial information for planetesimal and planet formation models. We present resolved dust…
Sensitivity and Performance of LBTI/NOMIC Spectroscopy: Prospects for 10- and 30-meter class Mid-IR Exoplanet Science
Brittany E. Miles, Steve Ertel, Kevin Wagner +1
Long wavelength infrared (8-13 m) spectroscopy is invaluable for detecting molecular features in the atmospheres of gas giant and terrestrial exoplanets. The nulling-optimized m…
LBT SHARK-VIS Observes a Major Resurfacing Event on Io
Al Conrad, Fernando Pedichini, Gianluca Li Causi +18
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes on Io's surface have been monitored from both spacecraft and ground-based telescopes. Here,…
Sudden extreme obscuration of a Sun-like main-sequence star: evolution of the circumstellar dust around ASASSN-21qj
Jonathan P. Marshall, Steve Ertel, Francisca Kemper +6
ASASSN-21qj is a distant Sun-like star that recently began an episode of deep dimming events after no prior recorded variability. Here we examine archival and newly obtained optica…
How much large dust could be present in hot exozodiacal dust systems?
